A Novel MAP3K1 Gene Mutation (c.556A>G) Associated with 46, XY Complete Gonadal Dysgenesis

Zhu Yilin , Chen Hong , He Minfei , Liang Li , Wang Chunlin

Introduction: Complex and ordered intracellular signal pathways play a significant role in sex determination in mammals, mediating the balance of gonadal development. A major pathway involved in the regulation of the male development is mitogen-activated protein kinase (MAPK) signaling pathway. To date, mutations of MAP3K1 gene have been found to account for approximately 15%-20% of 46, XY gonadal dysgenesis (46, XY GD)....

Objective: To determine the mutation in the SRY gene in a 46,XY complete gonadal dysgenesis patient with bilateral gonadoblastoma and coexisting dysgerminoma. Evaluate the functional consequence of mutated SRY gene in the tumor risk of 46,XY DSD.Methods and Materials: The proband was a 13-year-old girl who was admitted for examination due to undeveloped secondary sexual characteristics. She had no breas...

Premature Ovarian Insufficiency in Girls Caused by Autosomal Microdeletions: 3 Case Reports

Yuan Ke , He Minfei , Fang Yanlan , Zhu Jianfang , Liang Li , Wang Chunlin

Objectives: Premature ovarian insufficiency (POI) is mostly considered X chromosome abnormalities in child. Few of POI cases are associated with autosomal abnormalities. This study was to identify new genes involved POI in three girls.Methods: Three girls who came to the hospital because of no menstruation were investigated. They were 14, 15, and 14 years old. They did not find any breast tissue in their physical examination. Clinical data, sex hormones,...
